NASA conducted a comprehensive assessment of the potential threats to the health of astronauts from space missions, extravehicular activity (EVA) and hazardous exposures.. The risks of decompression sickness (DCS) and venous thromboembolism (VTE), as well as the role of patent foramen ovale (PFO), in these processes are being investigated.. The results of the expert group's work will help optimize safety protocols for future monthly and interplanetary missions, including those with the Artemis program.

DCS and VTE: new data for safe fields.

NASA's expert task force, made up of leading experts, analyzed the latest data from testing predictors for shipboard activity (EVA), episodes of decompression illness,. Integration updates with advanced research, including the assessment of PFO in the context of DCS and VTE risks in space flight.

The group's main recommendations include:.

Simplified selection criteria for tracking on Earth: subjects can no longer be excluded from tracking based on the presence of a glaucoma ovale (LVGE). Protocols may balance the safety and representativeness of the sample while ensuring that participants are kept informed of their status and associated risks..

Review of the risks of PFO before VTE: the consensus of experts is that the presence of PFO is not a relevant risk factor for the development of VTE or the development of embolism, which is similar to the internal jugular vein or cerebrospinal fluid.. Changing the criteria for selecting astronauts completely PFO through the VTE risk is not recommended.

PFO: don’t forget the factor of high risk, otherwise it will require respect.

Due to decompression illness, experts have concluded that there is no clear connection between the stage of detection of bulbs and the risk of DCS under the hour of high-altitude protocols, which include partial. Although the bulbs are minimized, their predictive value for DCS becomes negligible, especially for operations on the surface of the month.

A classification of risks associated with PFO has been established:.

“Small” PFO (1 or 2 steps) does not set a significant rizik.

Following the “great” PFO (3 stages and higher), the thoughts of experts grew to the point that the correction or exclusion of astronaut’s risks significantly changes the passage of venous gas embolism (VGE) to the arterial blood flow.

The group did not recommend universal screening or exclusion of astronauts with large PFOs, but advocated the importance of minimizing risks through protocol design and consistent data collection. As astronauts are assessed, they are informed of their status and advised of the possibility of PFO correction.

The need for clear clinical guidelines for taking medications before post-ship activities was also emphasized. Zocrema, protocols may cover the use of aspirin for the prevention of DCS and pain, as well as the use of analgesics (acetaminophen, ibuprofen, naproxen, celecoxib) until after EVA, fragments of these drugs can be masked.
